metal, extends at either end into a recess, G, cut out of the side' pieces A, which recesses are protected by suitable metallic shells, h', and there rests upon Indiarubber springs H.

A bolt, i, passes down through the side pieces A, and through said spring-bar, spring, and the stay-bar F', and is secured upon its lower tlueaded end by a suitable nut. This portion of the side pieces may be supported by proper metallic side, top, and bottom plates, j.

The stay-bar, made preferably of wrought metal,

extends from side to side from the outsides of the side pieces A. .lhe supporting-block h, which should be of wood, is tted closely between the s pring-barand the'stay-bar, and prevents'either from springing, and its ends, which come closely to the inner sides 'of the side pieces A, cover the recesses G and prevent the springs lin part from spreading laterally, and also yserve to prevent the intrusion of dust to said recesses.

The .hind wheels I ofthe wagon, turning as before described in the openings c in the side pieces A, rotate upon fixed hollow spindles, J, in Isuitable outer and4v inner boxes, Kand K'. These wheels are constructed with hubs, k, which do not extend longitudinally much beyond thetires or rims, and uponl the inner side of each -hub is a circular recess, k.

The spin dIeJ, preferably of cast metal, which is insorted into the lmb from the inside as the wheel stands in position for use, islargest upon its inner end, and has around it a flange, l, corresponding in" size and form with the recess k-, into which it is closely fitted. When thus fitted the wheel I is midway between the two ends of said spindle;

0n the side having 'the flange l, and midway be#` tween that and the. end of theg spindle, is another ange, m, encircling said spindle.

Ou the opposite or 'outside of the wheel the spin- (lle is turned down considerably smaller', and upon this'end, midway between the hub and the end of the spindle, is another flange, .1, encirclingsaid spindle.-

'Ihe spindle is held in place within said hub, and the hub securedl thereto, by means of screws passing tllrough the hub and through the flange l.

The box K is upon the outer under side of the side piece A, and is composed of upper and lower pieces, having central semicircular corresponding openings o in each,'and also a vertical groove, o', running cohtiuuously entirely around the walls of said opening,

of such a form and in such position as to receive the ilange u, above named.

- The box K', upon the inner under side of said side pieces A, is similarly constructed as the box K, and furnished with a. like groove, o", for the reception of the flange m. Suitable openings in said boxes aiord means for oiling. The boxes themselves are secured to the under sides of said side pieces A by means of suitable bolts passing down through said side pieces and the ends of saidbones, and properly threaded, and provided with nuts. 'Io the under side of the cross-bar B' is secured a bloclcL, provided with a. dependent circular boss, p, having ou its under side a recess, p'. This boss tits into a correspondlngrccess in the upper part M of the* ith-wheel, which is secured to the under side of the block L by means of suitable screws or bolts passing down through said cross-bar B', the block L, and the tlangesq, upon said part M. This part just named is cast in one piece, of steel or malleable iron, and has a boss, r, with sidewalls r', nearly vertical, but slightly beveled inwardly, a bottom, r", a little convex. an intei-nal cavity, s, corresponding 'to its external shape, and an opening, t, through the center of its bottom. '.lhis part M tits within and rotates in a lowenpsrt, N, ol' the filth-wheel. .lhis part N is n ring cast in one piece of suitable metal, having an internal circular opening, u, corresponding to thev boss r, which fits within it, and a auge, o, encircling it,by means of which it is bolted or otherwise secured to the houndblock 0. '.lhisv houndblock,'which is preferably of wood, has sunk into its center a circular recess, o', oorresponding to the bottom fr ofthe part M, and in the center of this recess another circular recess, v", through the center of which is an.opening,w, down through scid hound-block'and the fore axle P of .the wagon.

A bolt, Q, passes down through thc opening named in the part M, the `houndblock 0, and the axle P, and is secured upon its lower threaded end, beneath said axle, by a proper uut. This bolt has securedto it a disk, R, slightly concave upon its top, into which the bottom c ofthe part M fits, and the disk in turn lits closely into the recess o" in the hound-block.

The opening t, before named, in 'thc part M, is alittle larger than the diameter of the bolt Q, where it passes through it, for the purpose of allowing some play and rock to the fth-wheel.

Upon said bolt, within the cavity s, is a washer, 1, and above that thev bolt is-threaded and provided witlv a nut, 2, not screwed down very tightly, so as to permit af little play vertically and laterally to the fifthw'heel.

are covered by the boss p oi' the block L.

' The tongue S is connected'with the hound-block O, and the latter to the axle P, in a manner described in 4a former patent issued to me.A

The fore wheels l complete the enumeration of .parts belonging to this wagon.

In the construction' of' my device it will be noticed that nearly vthe entire weight of the load rests upon the spring-bar in the center, and thls in turn upou the springs beneath its ends, by means of which con-v trivance I dispense with the steel springs at either -end ol' thel wagon, which are very heavy, very cxpen sive, and continually liable to break; and at the same time I secure that' elasticity which is indispensableiu the proper carriage of bricks and fragile articles, and advantageous in the carriage of coals.

In connection with this arrangement for supporting and giving spring to the body of the wagon, my construction of frame allows it to be so dumped that the lower end of the, body will rest upon Athe ground. This construction,however, requires me to dispense with the 'hind axle to my wagon, which I'am able to do on account of the peculiar contrivances ofl the frame and the use ofthe metallic yoke-bar, vwhich give it sufficient support.

Being thus obliged to runl the hind wheels without an axle,'I am enabled to do this by the use ofthe peculiar spindles and bosses employed, iu which the -hollow of the spindles enables meto combine strength `with little weight, and to avoid all danger of heating, while the llanges on the spindles, turning in corresponding grooves in the boxes, tend to support the wheel and keep it always in proper vertical position.

By reason, however, of dispensing with springs to the forward part of my wagon, I am obliged to have suoli a fifth-wheel as may be safely operative, and so I use one which is exceedingly simple, strong, and cheap, which will bear the shocks imposed upon it and cannot readily get out of order.

I do not wish to be confined -to dumping or other wagons, in the use oir' such parts of' my deviceas are novel; but wish to employ them wherever they may be used bcneicialiy.

Having thus described my invention,

What I claim as new therein is- 1. In combination with the side pieces A of a wagon, the yoke-bar C, constructed and arranged substantially as described and shown.

v The upper ends of the bolt, the nut, and the washer `2. The means einployed `for supporting and giving elasticity of motion to awagon-body, consisting of the spring-bar F and India-rubber springs 1:1,t4he spring- .bar and springs bengieonstructed, arranged, and op-` erated substantially as described and shown.

3. The fifth-wheel M and N, constructed and a.r`

ranged substantially `as described and shown.

4. The hollow spindlesJ, provided with IemgeSI,

m, and n, in uonneccion with a. wagon-hub, when said spindles are constructed and `arranged, substantially as described end shown. l

1n testimony that I claim the foregoing. l have herel unto set my hand thisV 22d day of April, 1871.
